The Sprolink SG-UHD is a 4K multi-format video signal generator with HDMI, 3G-SDI, and SFP outputs, a 4.3-inch screen, SMPTE color bars, custom test patterns, and 16 channels of embedded audio. Call 844-687-4208 for help.
A pocket signal source for setting up, testing, and troubleshooting any video system.
Overview
The SG-UHD is a portable test signal generator for installers and live production techs. It outputs over HDMI, 3G-SDI, and SFP, drives independent 3G-SDI and HDMI 2.0 4K dual channels, and shows status on a 4.3-inch screen.
It includes built-in signals such as SMPTE color bars, supports linear testing, and lets you import custom patterns as test images. It carries up to 16 channels of embedded audio plus a 3.5mm stereo output. An FPGA design keeps it stable for long test sessions, and the metal enclosure adds durability, drop resistance, and better heat dissipation. Power is DC 12V or 5V over USB Type-C.

Why the SG-UHD
When a display, switcher, or long cable run is not behaving, a known-good signal source is the fastest way to find the fault. The SG-UHD puts HDMI, SDI, and SFP test signals, SMPTE bars, custom patterns, and embedded audio in one rugged, pocketable box, which saves real time on installs and live calls.
